直扩系统的抗干扰能力由其处理增益决定,当其处理增益不足以对抗强干扰时,则需寻找其他干扰抑制来提高系统性能。本文研究了一种直扩信号的干扰抑制算法,对其工作原理进行了分析,给出了干扰复制和门限算法,并讨论了其中的非线性运算的DSP实现问题。 相似文献

GPS高空气象探测技术比常规雷达探空技术性能更优。由于频段(国际电联规定的400
MHz气象频段)的限制,其信道重用、邻频干扰和其它干扰情况极为严重,令GPS探空系统
通信信道的质量极差。为此,采用RSCC级联编码方式进行信道编码。Matlab仿真结果表明,
在400 MHz载波频率、2 400 bit/s、5 dB信噪比的条件下,传输误码率降低到10
-3,数据接收率能够满足气象探空的要求。最后给出了采用TMS320VC5402的
通信模块硬件实现的编、译码核心部分。 相似文献

毫米波地面通信系统是典型的视距通信。目前我国使用的时统设备存在结构庞大、使用不够简便等缺点。GPS时统系统具有体积小、精度高、掉电不丢失数据等特点。利用GPS所提供的秒脉冲前沿为时间基准,通过DS3231把时间进一步细到微秒数量级,保证了跳频通信的可靠性和准确性。 相似文献

Nowadays the European Universities are worried about how to adapt higher education to the new European Higher Education Area,
as proposed in the Bologna Magna Charta Universitatum of 1998, and signed by 32 European Education Ministers. One of the key
points in this higher education reform was the introduction of new Master’s level curricula. These Masters will look for the
professional specialization and they will have to be adapted to the specific skills demanded by the society. This paper presents
the results from a cooperation project – funded by the AECI (International Cooperation Spanish Agency) and developed between
the University of Seville (Spain) and the Catholic University of Asuncion (Paraguay) – by about the planning of a new master’s
level curriculum in digital signal processing (DSP) area, taking into account the Bologna principles and the conclusions obtained
by the Career Space Consortium. A scientific method from social science, known as concept mapping techniques, was used to
perform this planning. Basically, the idea of concept mapping consists of compiling the opinion from actors belonging to different
environments (lecturers, researchers, workers, businessmen, etc.) related to DSP applications. The compiled data were statistically
computed to cluster the opinions of the different agents. The result will be a master’s level curricula adapted to the environment
requirements and the social settings. 相似文献
